A Paeroa bull named Sierra is deemed elite nationwide in on the Ranking of Active Sires (RAS) list for crossbred bulls.
Dairy farmers from across the country can now purchase Sierra's semen to inseminate their cows.
Staff from the dairy genetics co-operative Livestock Improvement Corporation (LIC) have identified a new Zealand's top bull for contract matings to be carried out nationwide.
The best of these calves were selected to enter LIC's Sire Proving Scheme which assesses the genetic merit of the bulls, the milking performance of their daughters and other assessment criteria over a number of years.
"Bulls with higher genetic merit sire cows with better milk production and other desirable traits," LIC said.
"Our breeders are absolutely essential to the work we do to achieve continual genetic gain for the benefit of the country's dairy herd," LIC chairman and Nelson dairy farmer Murray King said.
"They are dedicated to breeding superior livestock and have a real passion for it.
"They have a detailed and intimate knowledge of cow families, and a good eye for bloodlines." Premier Sires are responsible for siring about 75 per cent of the dairy herd in New Zealand.
King said LIC breeders have a strong awareness of what the future New Zealand cow should look like, in line with national breeding objectives.
"We want robust highperforming cows with longevity that every commercial dairy owner wants and is proud to own. In the current economic environment more than ever, it is important we have animals suited to New Zealand's competitive advantage - which is pasture-based farming systems." The dairy co-operative has recently cemented its position on Jersey Premier Sires bulls leader spreading the good news around dairy farmers who have chosen to get their jersey inseminations from the farmerowned co-operative.
The majority of the industry's top Jersey bulls are now within LIC's Premier Sires team.
Among a range of positive statistics on the Jersey RAS list, LIC has all of the top five bulls.
It also has eight of the top 10 and 11 of the top 15 bulls. Of the 11, nine are new graduates, which illustrates the change in LIC's momentum.
A Holstein Friesian bull named Beamer has also been as one of the LIC's top bull in its breed.
The co-operative is the largest artificial breeding company in the country, and is owned by 10 500 New Zealand dairy farmers.
Sierra, from Paeroa has been selected the top bull in New Zealand in on the Ranking of Active Sires (RAS) list for Crossbred bulls.
